Specification of Letters Patent.

Patented June 15, 1920.

Application filed October 27, 1919. Serial No. 333,588.

To all whom it may concern:

Be it known that I, SIMON GAINER, a citizen of the United States, and aresident of Chicago, Cook county, and State of Illinois, have inventedcertain new and useful Improvements in Sectional Springs, of which thefollowing is declared to be a full, clear, and exact description.

This invention relates to sectional springs and is in the nature of animprovement upon the, box spring shown and described in my prior PatentNo. 1,296,068, dated March AL, 1919. The principalobj ec't of thepresentinvention is to provide a spring for beds and other furniture, made upof plurality of sections, which may be readily secured together, anddetached from each other and having connecting means between the adjacentrows of springs of the several sections free from and movableindependent of any other-edge members of the spring. I have found fromexperience that better results are obtainedby making the connectingmembers between the adjacent rows of springs of the several sections,independent of the lengthwise extending edge members that usuallyconnect the springs, and in'the pres ent invention I tie together themarginal side rows of the spring sections so that when one marginal rowis depressed theadj acent row of the adjacent section will also bedepressed, more or less, without, however, effecting the marginallengthwise extending row of springs to such a great degree. In this wayI obtain greater comfort with the use of the spring-without sacrificingany of the beneficial results" obtained in a spring such as is disclosedin" my prior patent. The invention consists in the several novelfeatures hereinafter fully set forth and claimed. v

The invention is clearly illustrated in the accompanying drawings, inwhich:

Figure 1 is a plan, partly broken'out, of a sectional spring embodyingasimple form of the present invention; Fig. 2 is a side elevationthereof, partly broken out; Fig. 3 is an end View of the spring'lookingin the direction of the arrow 3 in Fig. 1 and showing the covering andupholstering omitted; Fig. 4' is a detail, vertical, longitudinalsection taken on the line 4-4 of Fig; 1 Fig. 5' is a detail, vertical,cross section taken onthelinje 5'5 of Fig. 41,; Fig. 6 is edema,vernea1, resss e ion taken on tical, cross section taken on the line 77in Fig. 1; Fig. 8 is a plan of a fragment of a slightly modified form ofthe invention and Fi 9 is a side elevation of the parts seen in Fig. 8.

Referring to said drawings, which illustrate a simple embodiment of thepresent invention, the reference characters A, B, C, designate threesections, which comprise a complete bed spring, and as said sections aresubstantially similar in construction, I shall proceed to describe oneof them, which description, it is'understood, applies to all.

A rectangular bottom frame is employed forsupporting the springs, whichare of the usual and well known coiled compression spring construction,and said frame is shown as comprising horizontal frame members 10connected by horizontal frame members 11. The frame members 10 extendlengthwise of the complete spring and the frame members 11 extendcrosswise thereof.

Secured to and projecting up from the frame members 10 are short postsor upright members 12, to the upper ends of which are secured bars orupper frame members 13 that extend lengthwise of the complete spring.

Secured to the lower frame members 10, 11 is a bottom 1% upon which aresecured coiled compression springs 15 of the usual construction employedin bed springs, the upper ends of said springs being tied together bywire or heavy cord, 16, as is usual in the construction of bed springs.

The springs 15 are usually arranged in rows in each section, as shown,and the marginal side rows 17, 18 (see Fig. 1) are connected at theirupper ends to crosswise ex tending bars 19, 20, preferably formed ofangle iron bars, which extend between the ends of the upper frame bars13. The springs may be secured to said bars by any suitable means, and Ihave illustratedwire clips 21 for this purpose. Each bar 19, 20 maycomprise a single bar if desired, but I prefer to make it up of a numberof sections as shown at 22, '23 arranged end to end and hingedlyconnected together by loops or other similar connections 24, whichextend through the horizontal webs of the angle iron bars, as is clearlyillustrated in Fig. 6. This arrangement permits the far end of onesection of any bar to be depressed considerably without correspondinglyde pressingthe entire bar, in other words, each bar is capable of beingdepressed at either end without materially depressing all of the springsconnected to the other section of the bar. Endwise movement of the bars19, is prevented by the end portions of the upper frame bars 13.

Each cross bar 19 is provided with bar connecting devices, here shown ascomprising pins 25, which project laterally therefrom and each cross bar20 is provided with sockets 26 adapted to receive said pins to therebyconnect together the adjacent 7 cross bars 19, 20. If desired saidsockets may be formed by providing holes in the bar 20 or they may bemade of separate fixtures secured in holes in the cross bars 20. For thepurpose of guiding the pins to the holes in the sockets when assemblingthe several spring sections into a complete spring, the upper ends ofthe socket members 26 are formed'with diverging end portions 27 arrangedalong the outer faces of the cross bars 20, which act to guide the pins25 when one section is moved down along the other section to couple thetwo together. Obviously, many forms of con nections may be providedbetween cross bars 19, 20 to secure them together so that they will movein unison, but the one illustrated is very simple and serves thepurpose. To prevent separation of several sectionsafter they have beenplaced together with the pins in the sockets, provide hooks or latches28 on the sections, which hook over pins or eyes 29 on the adjacentsections as is clearly illustrated in ig.2.

The sectional spring shown and described may be used with the ordinarymattress as is customary or if desired the sections may be upholsteredto form a sectional box spring, and in the drawings I have illustratedcushions or upholstered material 30 above the springs 15 and'the usualticking 31 (see Fig. 7 covering the upholstering material and frame workof the springs.

In the modified form illustrated in Figs. 8 and 9, the top bars 13 aremade shorter than the lower bars 10 to permit the cross bars 19 20 toextend the full width of the spring, and in this case I have shown hooksor latches 28" secured to one cross bar and arranged to hook over pinsor eyes 29 upon the adjacent cross bar. This arrangement preventsseparation of the spring sections and positively connects together thetwo bars 19 20". It is to be understood that r the springs 15 aresecured to thecross bars as in the preferred form and that the crossbars may have the pin and socket connecting devices or other fixturesfor connecting them together.

l/Vhile the invention has been shown as applied to what is known as hardedge box springs, it may be applied equally as well to spring edge boxsprings, that is to say,

the upper frame members 13 and supports 12 may be omitted and the outeror end rows of springs 15 of each section may be connected by a wire orrod as is customary in bed springs or box springs. Moreover while theinvention has been shown as applied to a bed spring it may be appliedequally, as well to the springs of couches, settees, davenports, seatsor other analogous articles where sectional springs may be employed.

The advantages of the sectional spring embodying the present inventionare many. In place of carrying about an entire spring, each section maybe easily handled separately and put in position and connected with theothers to make up the complete spring. Moreover when the weight of thebody is applied to any cross bar the adjacent portion of the contiguouscross bar and springs connected therewith are moved in unison therewithwithout, however, disturbing the distant springs or without moving theentire marginal frame asis the case in the sectional spring of my priorpatent. It is to be understood that while I have shown three sections ascomprising a whole spring two or more may be used to obtain the sameresults. The frame may be constructed of wood or metal as desired, foruse on wood or metal beds or other furniture.

More or less variation of the exact details of construction is possiblewithout departing from the spirit of this invention; I desire,therefore, not to limit myself to the exact form of the constructionshown and de- 100 scribed, but intend, in the following claims, to pointout all of-theinvention disclosed herein.

I claim as new, and desire to secure by Letters Patent:
